HANS C. SCI-IROEDER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE GOSS PRINTINGPRESS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SHEET-ASSEMBLING MECHANISM FOR PRINTING-PRESSES.

To all whom it may concern:

Be it known that I, HANS C. Sormonnnn, a subject of the German Emperor,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Sheet-AssemblingMechanism for Printing-Presses, of which the following is aspecification, reference be ing had to the accompanying drawings.

This invention relates to sheet assembling space saved but a moreconvenientand ac-' cessible form of such delivery mechanism is provided.

Other objects of my invention are to provide a new and improved form ofsheet assembling mechanism in which a number of webs are gatheredtogether and cut-intosheets forming the main body of the paper, in whichinsert sheets, after being fed to a suitable table, are folded centrallyand thus folded are brought into association with the main sheets inposition to be upon the inside of the folded product and in which coversheets may be associated with the main sheets and insert sheets in sucha position as to be on the outside of the-folding product.

Referring to the drawin s,-Figure 1 is a front elevationdiagrammatically illustrating my invention Fig. 2 is a side elevation;and Fig. 3 is an enlarged detail, being a side elevation of the sheetfolding and forwarding mechanism of the cover sheets. Referring to theseveral figures of the drawings, in which corresponding parts areindicated by like reference characters,-

4 indicates the main frame of the machine. 5 indicates the usual rollerjournaled in the main frame, over which the webs 67891011 are led. Asshown in the drawings, there are six sections of the web. Of course, thenumber may be increased or diminished and it is immaterial whether theycome from six separate webs or from one or more webs slit into sectionsin any well-known way. Passing over the Specification of Letters Patent.

guide-rollers the webs pass over angle-bars 12 of the well-known formand description by which they are deflected and passin over suitableguide rollers as 13 are broug t together in registry and associatedbetween registering rolls 14 in the well-known manner. Passing theregistering rolls 14 in registry the webs pass between cutting cylinders1516 where they are severed transversely in the well-known manner andare led between suitable guide-rollers as 17 to a collecting cylinder18. The sheets severed from the superposed webs are collected upon thecollecting cylinder 18 in any well-known and approved manner forming ofitself no part of my invention. When a sufficient number are collectedthe lead edge is releascd from the grippers 19, with which thecollecting cylinder is provided, after the lead edge has passed roller20 and the sheets pass between guide-blocks 2122 downward and forwardadjacent to gripper cylinder 23 to'be associated with the insert sheetsas hereinafter described.

Referring to Fig. 2, where it is best shown, 24 indicates a suitablesheet forwarding mechanism, preferably such as that of the well-knownCross type, which is adapted to forward the insert sheets 25, which havebeen previously printed, in the well-known manner. The sheet forwardingmechanism 24 is, as is shown in Fig. 2, located within the main frame 4and directly behind a fold ing and foiwvarding mechanism hereinafterdescribed. One of these forwarding mechanisms is placed upon each sideof the machine behind the folding devices hereinafter described,although only one is shown in Fig. 2 of the drawings to avoid undulycomplicating the drawings. The sheets are delivered by the sheetforwarding mechanism 24, one at a time, and in a direction parallel withthe run of the main webs 6 to 11, inclusive, into tape paths 2627 bywhich the sheets are fed one at a time forward upon a folding table 28against a stop 29 between guiding ledges 30 (see Fig. 1). Actuated atsuitable intervals by any well-known mechanism a folding blade 31operates to tuck the central margin of the sheet fed upon table 28between folding rollers 32 into tape paths 3334 by which the sheetscentrally folded are fed down upon .a table 35 against the stop 36,which is adapted to be raised at suitable intervals by any well-knownmecha- Applicationfiled February 17 1912. Serial No. 678 351.

. t REISSUED nism. At suitable intervals the gripper cylinder 23 engagesthe lead edge of the folded sheet and carries the same around 4described, and located, as has been described above, directly behind thetable and within the framework of the press.

37 indicates a folding tucking blade,

which, operated by mechanism, hereinafter described, at suitableintervals folds the,

sheet centrally in the direction of its run between folding rollers 38.By means of tape paths 3940 the folded sheet is led to a table 41 andbrought against a stop 42, which will be hereinafter more fullydescribed.

'43 indicates rollers above the table 41.

44 indicates a pressure roller adapted to co-act with roller 43 atsuitable intervals and which is raised so as to co-act with roller 43 atsuitable intervals in the manner hereinafter described. Whenever therollers 43-44 are brought into operative relation and the stop 44 isremoved at suitable intervals the sheets are fed into tape paths 45-46and the parts are so timed that the lead edge of this cover sheet willbe brought into registry with the lead edges of the main sheets and theinsert sheets, brought together as above described, and below the mainsheets' By means of these tape paths the associated insert sheets, mainsheets and cover sheet are brought together upon a table 47 against aregistering stop 48 from which they are folded by the usual foldingblade as 49 operated in the well-known manner between folding rollers 50to any suitabledelivery mechanism as delivery cylinder 51 and tape paths52. The cover sheet-s may be of only one-half width transversely oftheir run in which case, of course, they will not be folded. In thiscase they are fed upon the left hand side (see Fig. 1) of the table 36.The folding blade 37 in this case acts to push the side edge of thesheet between rollers 38-39, the sheet being forwarded into the bite ofrollers 38 by a movable pressure roller 53 (see Fig. 3) hereinafterdescribed.

Referring to Fig. 3, 53 indicates a roller which is mounted upon arms 54on a rockshaft 55 and is adapted, when the shaft is rocked ashereinafter described, to press upon the surface of the sheet when onlya single width sheet is used for the cover as last above described. 56indicates an arm on rock-shaft 55 which, by means of an arm 57, isoperated by a cam 58 on shaft 59. lhe

cam 58 is so shaped as to move the arm. 57

to rock the shaft 55 at suitable intervals to bring the roller 53 int-ocontact with the paper and coiiperate with the folding blade 37 as abovedescribed. Referring to the same drawing, the folding blade 37 ismounted upon an arm 78 on rock-shaft 79, which is rocked by arm 60 andlink 61 operated by a suitable cam as 62 on the shaft 59. The cam is soarranged that the knife will operate at suitable intervals to forwardthe sheet whether folded or not folded to stop 42. The stop 42 ismounted upon an arm 63 on a rock-shaft 64 journalled inanysuitable wayin a frame and provided with rockarm 65 which is operatedby arm 66 andcam 67 on the shaft 59. As is best shown in Fig. 3, the stop 42 isprovided with a guide 68 which extends outward from the stop and bendsdownward and inward toward it suitable intervals to permit the sheet tobe forwarded in time for its lead edge to come into registry with themain sheets and insert sheets as above described. The forwarding of thesheets at "suitable intervals when the stop is raised is effected, asstated above, by rollers 43 and 44, of which the roller 43 is fixed'andthe roller 44 movable. As is best shown in Fig. 3, the shaft of theroller 44 is spring seated upon arm 69 on a rock-shaft 71. The rockshaft .71 is operated by another arm 72 and link 73 and cam 74 on theshaft 59. The cam 73 is so shaped and timed as to rock the shaft 71 andbring rollers 44 into operative relation with rollers 43 at suchintervals as to forward the cover sheet into the tape paths 45-46 andmeet the main sheets and insert sheets with their lead edgessubstantially together. That is to say, when all the sheets, the insertsheets, the

collected main sheets and the cover sheet are brought together at thelower side of delivery cylinder 23 into the bite of the tape paths 45and 46 they are substantially in register and associated together. Theregistry is completed and the sheets brought into proper association fortheir final fold by being brought against the stop 48 as abovedescribed. A
